5.2.3 Command line options

usage: qemu-i386 [-h] [-d] [-L path] [-s size] program [arguments...]
-h
Print the help
-L path
Set the x86 elf interpreter prefix (default=/usr/local/qemu-i386)
-s size
Set the x86 stack size in bytes (default=524288)

Debug options:

-d
Activate log (logfile=/tmp/qemu.log)
-p pagesize
Act as if the host page size was 'pagesize' bytes

Environment variables:

QEMU_STRACE
Print system calls and arguments similar to the 'strace' program (NOTE: the actual 'strace' program will not work because the user space emulator hasn't implemented ptrace). At the moment this is incomplete. All system calls that don't have a specific argument format are printed with information for six arguments. Many flag-style arguments don't have decoders and will show up as numbers.
